Scott Kelly's fame continues to rise.

The astronaut participated in a Q&A session with fans on Reddit over the weekend and many gave the Houston resident (when he isn't in space, of course) praise.

The questions varied from Kelly's love of Legos to urine acid cleanup missions to why he always crosses his arms in space (so they don't awkwardly float in front of him). And a few commenters got a few jokes into the tread.
